Ubuntu 20.04 LTS / 22.04 LTS / 23.04 / 23.10 : curl vulnerabilities (USN-6535-1)

critical Nessus Plugin ID 186615

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6535-1 advisory.

 Harry Sintonen discovered that curl incorrectly handled mixed case cookie domains. A remote attacker could possibly use this issue to set cookies that get sent to different and unrelated sites and domains.
 (CVE-2023-46218)

 Maksymilian Arciemowicz discovered that curl incorrectly handled long file names when saving HSTS data.
 This could result in curl losing HSTS data, and subsequent requests to a site would be done without it, contrary to expectations. This issue only affected Ubuntu 23.04 and Ubuntu 23.10. (CVE-2023-46219)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
